Happy Birthday, Wilbur Wright of the Wright Brothers! Their journey to achieve human flight began in 1878 after their father gifted them a rubber band-powered toy that flew across the room.
Good catch. Also born on this day, Charles Fefferman, one of the most notable child prodigies ever in mathematics. (He was named full professor at the University of Chicago when he was 22, and remains the youngest person ever to be named a full professor at an American university.)
